Turning Inserts – Heavy Duty (HDT)
Fire kraftige spånriller — TCH, HD2, HD5, HD8 — plus 909+ skrubdrejning og et dedikeret titanium-sortiment.
Galtonas HDT-serie udvider programmet for negativ størrelsesdrejning til krævende, kraftig drejning — fra medium skrubdrejning op til fuld afbrudt spåntagning.
Fire dedikerede spånspor skalerer med spåndybde: TCH (2.5–10 mm), HD2 (1.5–12 mm, ny skarp positiv geometri til højstyrkestål), HD5 (2–12 mm) og HD8 (2.5–12 mm, klassificeret til ensartede, inkonsistente *og* afbrudte spåner).
Sporet 909+ tilføjer dækning af medium og skrubdrejning på tværs af CNMG, SNMG og TNMG former plus runde RCMT skær i GTCP125, GTCP135 og støbejernsspecifikke GTCK120 kvaliteter.
Inkluderer også et dedikeret titaniumdrejesortiment ("S15") med IPE+ spånbrydergeometri på tværs af CNMG, DNMG, SNMG, TNMG, VNMG og WNMG skærformer.
HD8 — heaviest chip groove, interrupted-cut rated
HD8 Chip Groove
Heaviest chip groove in the range — steel "P25", also rated for interrupted cuts.
Example: CNMM 190616SN-HD8. Depth of cut 2.50–12.00 mm, feed 1.20–0.35 mm. Suited to consistent, inconsistent, and interrupted cutting depth.
